What I'm looking for

I’m looking for a team that works in Agile, values secure and scalable architecture, and gives me ownership across React performance and reliable Node.js backends—so I can build, optimize, and ship smooth software.

I’m a Full Stack Developer with hands-on experience delivering real-world projects, specialized in React with a strong focus on performance (60 FPS) and scalable backend architectures using Node.js and RabbitMQ. I’ve built secure, enterprise-minded solutions, including data security work with C# encryption, SQL Triggers, OAuth, and JWT.

In my recent work, I managed ~50 daily tickets with 95% CSAT in an enterprise environment, identifying recurring issues and partnering with development teams to improve reliability. I also refactored a monolithic application into decoupled modules using asynchronous messaging with RabbitMQ (improving consistency and scalability), and built a React music player with a real-time audio visualizer running at 60 FPS using Web Audio API and Canvas 2D.
